"I got real emotional and real excited and it was unfortunate that James had to get hit with an unintentional elbow. The Thunder, they're playing for a championship this year, so I really hope that he's OK. I apologize to the Thunder and to James Harden."

If you read between the lines here, Metta is saying he got hyper-emotional after a big dunk and completely lost control of himself. As a result, he thoughtlessly threw an elbow. And now he'll almost definitely miss a bunch of playoff games.
